Your copy-and-paste prompt
Replace the [brackets] with your details, then paste this into your assistant.
Build an original browser instrument with this mood: [mood]. Its sounds should feel [three descriptive words], and its visual world is [theme, such as rain on a space station]. I want to play it without knowing music theory.
Use synthesized sound through Web Audio, not downloaded songs, samples or a paid API. Create six playable notes or sound gestures, two expressive controls and a simple eight-step loop sequencer. Choose a small, coherent sound palette. Map controls to both the keyboard and visible touch buttons. Make the instrument understandable by trying it, with a short control legend and one starting preset.
Audio must begin only after an explicit start action. Include a conservative master volume, an obvious mute or stop-all control, and a reset. Avoid flashing visuals; support reduced motion. Let me save and reload the sequencer pattern and control settings as a small file. Prefer one self-contained HTML file with no external dependencies.
Check that start, mute, reset, pattern save and reload behave correctly. If you cannot listen to the output, say that sound quality still needs my review. Return the playable file, editable source and a short guide to changing the sounds. Do not deploy it or describe it as a tested instrument unless you actually tested those behaviors.

What the result could look like
The Rain Station
An illustrative instrument could combine soft bell tones, filtered noise and a drifting eight-step pattern. You would shape the mood with two controls and save the pattern you liked.
Illustrative example. This is not an observed result or a verified recommendation.
Make it more you
Make a version that sounds like a sleepy robot, a sunlit greenhouse or an elevator between imaginary planets.
